Arizona government health insurance comes in two main forms: the Arizona Health Care Cost Containment System (AHCCCS), which is the state’s Medicaid program, and subsidized private plans sold through the federal Health Insurance Marketplace at HealthCare.gov. AHCCCS is for individuals and families at or below 133% of the federal poverty level. Marketplace subsidies help people who earn too much for Medicaid but still need help paying premiums. Which one you qualify for depends almost entirely on household size and income, and for 2026 the rules on both sides have shifted enough that it is worth checking even if you were enrolled last year.
Who Qualifies for AHCCCS in 2026
AHCCCS uses Modified Adjusted Gross Income (MAGI) — the figure from your federal tax return — to decide most eligibility. You also need to be an Arizona resident and either a U.S. citizen or a qualified noncitizen with eligible immigration status. Noncitizens who do not meet the immigration requirement can still get coverage for emergency medical services under certain AHCCCS categories.
The income ceilings for 2026, as a percentage of the federal poverty level, break down by group:1AHCCCS. FPL and Income Eligibility Chart
- Adults ages 19 to 64: 133% FPL
- Parents and caretaker relatives: 106% FPL
- Pregnant women: 156% FPL
- Children under age 1: 147% FPL
- Children ages 1 to 5: 141% FPL
- Children ages 6 to 18: 133% FPL
- KidsCare (children under 19): 225% FPL
In dollars, the 2026 federal poverty level is $15,960 for a single person and $33,000 for a family of four.2U.S. Department of Health and Human Services. 2026 Poverty Guidelines – 48 Contiguous States That means a single adult qualifies for AHCCCS with income up to roughly $21,227 a year, and a family of four can qualify for KidsCare for their children with household income up to about $74,250.1AHCCCS. FPL and Income Eligibility Chart
People who are 65 or older, blind, or living with a disability may qualify under different rules that look at both income and countable assets. The Arizona Long Term Care System (ALTCS), which covers institutional and home-based long-term care, and the Freedom to Work program for employed individuals with disabilities each have their own financial criteria.
What AHCCCS Pays For
AHCCCS delivers care through a managed care model. You enroll in a health plan under contract with the state, and that plan coordinates your care through its provider network.
The benefit package is broad: doctor visits, hospital care, lab work, X-rays, prescriptions, immunizations, surgery, emergency care, behavioral health treatment, family planning, dialysis, and transportation to appointments. Children under 21 get added coverage for dental treatment, vision exams and glasses, and hearing exams and hearing aids. Adults 21 and older get emergency dental coverage up to $1,000 a year.3AHCCCS. Covered Services
Behavioral health is more extensive than most people assume. AHCCCS covers crisis intervention, residential treatment, substance abuse programs, rehabilitation services like supported employment, and support services including case management and housing assistance.3AHCCCS. Covered Services
How to Apply for AHCCCS
Before you start, pull together recent pay stubs, your most recent tax return, a driver’s license or state ID, and a utility bill or lease showing your Arizona address. Those documents cover identity, income, and residency for most applicants.
The fastest route is the Health-e-Arizona Plus (HEAplus) online portal. A single application there also covers nutrition assistance and cash assistance, and the system verifies Social Security numbers and some income data automatically.4Arizona Department of Economic Security. Health-e-Arizona Plus Application for Benefits You can also apply in person at a Department of Economic Security (DES) office or by mailing a paper application.
Apply sooner rather than later if you already have medical bills. AHCCCS coverage can be retroactive to your application date, and under current rules through the end of 2026 that retroactive window extends up to 90 days before you applied. Starting January 1, 2027, a new federal law shortens that window to 30 days for Medicaid expansion enrollees and 60 days for other eligibility groups.
Keeping AHCCCS Coverage Through Annual Renewal
AHCCCS redetermines your eligibility every year, and since the end of the COVID-19 continuous coverage provision these renewals are no longer automatic. The state sends a renewal notice by mail, or electronically if you opted in, and you have 30 days to respond with updated income and household information.
This is where a lot of Arizonans lose coverage they still qualify for. If you do not respond, AHCCCS can terminate your coverage even if nothing about your income has changed. Keep your mailing address and phone number current in HEAplus, watch for mail from AHCCCS or DES, and answer the renewal on time. You can reapply if you lose coverage, but there will likely be a gap when you are uninsured.
Marketplace Subsidies When You Earn Too Much for AHCCCS
If your income is above the AHCCCS thresholds, HealthCare.gov is the next place to look. The main form of help is the Premium Tax Credit, which lowers your monthly premium.
Two things changed for 2026 that directly affect what you will pay. The enhanced premium tax credits in place from 2021 through 2025 expired on January 1, 2026.5Congressional Research Service. Enhanced Premium Tax Credit and 2026 Exchange Premiums First, the 400% FPL income cap on subsidies is back. To qualify in 2026 your household income must fall between 100% and 400% of the federal poverty level — roughly $15,960 to $63,840 for a single person, and $33,000 to $132,000 for a family of four.2U.S. Department of Health and Human Services. 2026 Poverty Guidelines – 48 Contiguous States Second, the share of income you are expected to contribute toward your benchmark plan went up in every income bracket, which shrinks subsidies even where premiums held steady.
If you received advance premium tax credits in 2025 and did not update your marketplace application for 2026, your monthly cost may have jumped.
Choosing a Marketplace Plan
Plans are grouped into metal tiers that describe how costs are split between you and the insurer across a typical population:6HealthCare.gov. Health Plan Categories – Bronze, Silver, Gold and Platinum
- Bronze: plan pays about 60%, you pay about 40%. Lowest premiums, highest out-of-pocket costs.
- Silver: plan pays about 70%, you pay about 30%. Mid-range on both.
- Gold: plan pays about 80%, you pay about 20%. Higher premiums, lower costs when you use care.
There is a reason enrollment counselors push Silver plans so hard for people in the lower income range. If your household income is between 100% and 250% of the federal poverty level, a Silver plan automatically includes cost-sharing reductions (CSRs) that lower your deductible, copayments, and out-of-pocket maximum. You do not pay extra for them. With CSRs, a Silver plan can cover anywhere from 73% to 94% of your costs, depending on where you fall in that income range.6HealthCare.gov. Health Plan Categories – Bronze, Silver, Gold and Platinum A CSR-enhanced Silver plan can beat a Gold plan on out-of-pocket costs while still charging a lower monthly premium.
When You Can Enroll in a Marketplace Plan
Marketplace coverage follows a fixed calendar. For 2026 plans, open enrollment ran from November 1, 2025 through January 15, 2026.7Centers for Medicare and Medicaid Services. Marketplace 2026 Open Enrollment Fact Sheet Outside that window, you generally cannot enroll until the next open enrollment opens in the fall.
The exception is a Special Enrollment Period triggered by a qualifying life event. Common triggers include:8HealthCare.gov. Qualifying Life Event (QLE)
- Losing other coverage — a job-based plan ending, aging off a parent’s plan at 26, or losing Medicaid
- Household changes — marriage, divorce, having or adopting a child
- Moving to a different ZIP code or county
- Gaining U.S. citizenship, leaving incarceration, or income changes that affect what coverage you qualify for
A qualifying event generally gives you 60 days to enroll or change plans. If you lose AHCCCS during your annual renewal because your income is now too high, that loss itself qualifies you for a Special Enrollment Period on the marketplace.
AHCCCS, by contrast, takes applications year-round. If your income drops below the AHCCCS limits mid-year, you can switch out of a marketplace plan at any time.
Reconciling Your Premium Tax Credit at Tax Time
If you take advance premium tax credits during the year, you have to reconcile them when you file your federal taxes. The marketplace sends Form 1095-A by mid-February showing your monthly premiums and the advance credits paid on your behalf, and you use it to complete IRS Form 8962.9HealthCare.gov. How to Reconcile Your Premium Tax Credit
If your actual income came in lower than your estimate, you get a larger refund. If it came in higher, you owe back some or all of the excess credit. Here is the part that catches people: for tax years beginning in 2026, there is no cap on the repayment amount.10Internal Revenue Service. Questions and Answers About the Premium Tax Credit In earlier years the repayment was capped based on income. That cap is gone, so the full difference between what you received and what you qualified for will hit your return.
The defense is to report income changes to the marketplace as they happen — a raise, a side job, anything that moves the number. Updating your application during the year keeps the subsidy aligned with your actual earnings.
If You Are Denied Coverage
Both programs give you a right to appeal. For AHCCCS, you have 35 calendar days from the date on your decision letter to file an appeal, by mail, fax, email, phone, in person, or through HEAplus. If that deadline lands on a weekend or state holiday, it extends to the next business day. If you miss the window, you can still request a “good cause” hearing by explaining why you filed late — illness and not receiving the decision letter are among the accepted reasons.11AHCCCS. 1702 Eligibility Appeal Requests
For marketplace decisions, you have 90 days from the date on your eligibility notice. You can appeal a denial of enrollment, a subsidy amount you disagree with, a denied Special Enrollment Period, or a disputed coverage start date. Filing after 90 days is still possible if you explain the delay.12HealthCare.gov. What Can I Appeal
If you are not sure which program fits your household, apply through HEAplus or HealthCare.gov and let the system sort it out. Both front doors evaluate your information and route you to AHCCCS or the marketplace based on what you qualify for, so you do not have to decide in advance.
